5.8 Repair Tips
If one of the errors of the error buffer points to a defective
supply, then the supply-panel must be send for central repair.
If the symptoms (still to be communicated; e.g. when VS-value
is too high some pixels do not extinguish, when VS-value is too
low some pixels do not enlighten) match with a possible
misalignment of a supply-line, this supply-line could be
checked, and re-aligned.
Only do this if there is a slight spec-violation.
In case it does not help, re-align to the previous wrong setting,
to keep cause-image in tact, for central repair workshop.
Replace supply panel by a new one, and match the supply with
the pdp. (See alignment instructions in chapter “Alignments”).
